I wanted to ask you some general questions about some settings HiViz ...
I mainly have questions centering around VTT CPU Voltage, CPU PLL Voltage, and CPU VCCSA Voltage. It seemed that my system was not stable at all when VTT and PLL were both on Auto. When I set VTT manually to it's default value and set PLL voltage manually to it's default +0.00625V it stabalized it a lot. Do you think it was my manual setting of the voltages that had the effect, or will changing the PLL voltage slightly have a large effect on stability? Auto does not always mean that a single value will be used. Rather a generic set of values will be used depending to load or need. Once you set a voltage most of the time that is it.
PLL will have effects but each CPU will react differently to the increase, or decrease in voltage. The main effect of PLL for the overclocker is the heat that increasing PLL results in. With SB for example some folks were able to increase their Air cooled overclock by lowering the PLL - my one CPU was happy with 1.55 PLL
Also I'm not really sure what VCCSA voltage does but it seems to have an offset system just like VCore. Is there any reason for me to mess with that if things are still crashing? Again you can experiment with what your unique CPU needs, so it is nearly impossible for me to answer this question in any meaningful way. What I can suggest is read the guide that Raja wrote where he goes into some depth as to the purpose and ways to use each setting.
What I'm thinking is that maybe I could even get 0.010 VCore offset to work if I fine tune some of these voltages to keep it stable. Do you think it is best to find the absolute lowest VCore and fine tune these other voltages, or is tuning these voltages not much different than changing VCore? The additional voltage that you have made available using the vCore will only be used as and when it is needed. Let me try and explain it this way. What you are doing is creating a reserve in case needed.
Also, in Raja's guide he says he recommends a VCCSA Load-Line Calibration setting of medium for most overclocking. I believe mine has been left on Auto, so I just wondered if that would change anything. Yes I agree with Raja, I prefer to set my LLC rather than leave it on auto. Medium is a good balanced level. I do not advocate high or extreme.
I played a round of BF3 at the settings I listed in my last post that I thought were most promising and it made it through the whole round without crashing. If those settings don't give me any trouble today I may bump offset down to 0.010 and see just how low VCore I can run 4.8 with 😄
